[0023] Working process: when the first prefabricated part 2 and the second prefabricated part 3 are connected and fixed, one end of the double-headed screw 7 is connected to the fixing part 1. After the first prefabricated part 2 is inserted into the second prefabricated part 3, the other end of the double-headed screw 7 passes through the fixing tube 4, and the locking cap 8 is rotated. The locking cap 8 is connected to the double-headed screw 7, so that the locking cap 8 is in close contact with the retaining ring 5, thereby fixing the double-headed screw 7, and then tightening the first prefabricated part 2 through the fixing part 1 to connect and fix the first prefabricated part 2 and the second prefabricated part 3. The two retaining rings 5 are in contact with the locking cap 8 and the fixing part 1 respectively. The two retaining rings 5 protect the two ends of the through hole, so as not to squeeze the concrete on the through hole port, thereby avoiding the concrete on the through hole port from being crushed, thereby improving the connection effect of the prefabricated parts.
[0024] Example 2
[0025] After the fixing member 1 is fixed to the first preform 2, the outer wall of the fixing member 1 contacts the first preform 2. Since the outer wall of the fixing member 1 is smooth, the connection strength between the fixing member 1 and the first preform 2 is poor.

[0026] Example 3
[0027] After the locking cap 8 fixes the stud screw 7, the locking cap 8 and the stud screw 7 are connected by threads. After the second preform 3 is vibrated, the vibration is transmitted to the stud screw 7, causing the locking cap 8 and the stud screw 7 to move relative to each other, thereby reducing the fixing effect of the locking cap 8 on the stud screw 7.
